Racial Differences In The Association Of Insulin Resistance With Risk Of Incident Heart Failure In Participants Of Regards, Nirav Patel
All ETDs from UAB
Background: Insulin resistance is linked to the development of heart failure (HF). However, there is limited understanding of the racial differences in the association of insulin resistance with the risk of incident HF among individuals without diabetes. Objectives: In a US national cohort of Black and White participants, we sought to evaluate: 1) the relationship between insulin resistance with incident HF participants, and 2) whether there are racial differences in the association of insulin resistance with HF. Methods: We examined >16,000 participants without HF and diabetes at baseline from the REGARDS cohort. Cox regression modeling was used to assess the …

Cardiovascular disease risk is higher among adult with diabetes than those without diabetes. This increase in risk may vary by race, sex, and neighborhood characteristics. Recent US data showed a resurgence in stroke and coronary heart disease (CHD) among adults with diabetes, and an increase in heart failure (HF) mortality. Therefore, this dissertation investigated how cardiovascular disease risk may vary by race, sex, and neighborhood characteristics for adults across the glycemic spectrum.Data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study, an ongoing prospective cohort of 30,239 Black and White adults age 45 years at baseline (2003-07) …
Influence Of Race, Gender, Rurality, And Dyadic Health On Symptom Pattern Trajectories In Persons With Advanced Heart Failure, Macy Lynn Stockdill

Individuals living with heart failure experience a high symptom burden that must be addressed to improve their quality of life as well as the quality of life of their family caregivers. This is a challenging task as different situational and individual factors, including clinical/physiological factors and cultural factors, can affect an individual’s symptom experience. The purpose of this dissertation study was to examine existing symptom pattern trajectories and associated factors (sociodemographic, clinical/physiological characteristics, dyadic health) among a sample of under-resourced and racially diverse older adults with advanced heart failure living in the Deep South. This purpose was accomplished through four …
Biological Pathways And Processes Underlying The Cardiac Regenerative Response Post-Injury In Small And Large Mammals, Eric Yang Zhang
Biological Pathways And Processes Underlying The Cardiac Regenerative Response Post-Injury In Small And Large Mammals, Eric Yang Zhang

Mammalian cardiomyocytes exit the cell-cycle shortly after birth. Consequently, the adult heart is unable to properly compensate for cardiac muscle lost to injury. As such, heart failure has remained the leading cause of death in the developed world for more than three decades. In this work, we illustrate our findings in using novel in-vivo animal models to examine two regenerative phenomena observed following myocardial injury:i.) neonate cardiomyocyte proliferation in large mammals ii.) the ‘paracrine effect’ as mediated by mesenchymal stromal cells In i.) we use a large animal model of myocardial injury during the early postnatal develop-mental stage to establish …
Heart Failure In A Contemporary Biracial Cohort, Matthew Mefford
Heart Failure In A Contemporary Biracial Cohort, Matthew Mefford
All ETDs from UAB
Heart failure (HF) is the inability of the heart to meet the perfusion needs of the body. HF is a leading contributor to the burden of cardiovascular disease (CVD) and remains a public health concern. Hypertension is a major modifiable risk factor for the prevention and management of HF. Hypertension develops earlier, is less controlled, and has a stronger association with some CVD and renal outcomes among blacks versus whites. These disparities may extend to HF. In addition, adults with HF often have complex treatment regimens due to multimorbidity, making medication adherence an issue. The goal of this dissertation was …
The Role Of Macrophages In Pressure-Overload Induced Cardiac Remodeling, Bindiya Dinesh Patel
The Role Of Macrophages In Pressure-Overload Induced Cardiac Remodeling, Bindiya Dinesh Patel
All ETDs from UAB
Cardiac pressure-overload is a state of increased hemodynamic load and is initially characterized by concentric left ventricular (LV) hypertrophy, but can transition to eccentric hypertrophy and adverse LV remodeling leading to heart failure (HF). Cardiac remodeling during pressure-overload is accompanied by dysregulated collagen deposition, cardiomyocyte hypertrophy, and increased inflammatory signaling. Both clinical and preclinical studies have documented increased expression of inflammatory cytokines and leukocyte infiltration in the pressure-overloaded heart, indicating inflammatory mechanisms are active during cardiac remodeling. Despite the well-known link between leukocyte infiltration and exacerbated tissue injury, the role of innate immune cells, particularly monocytes, macrophages and dendritic cells, …
Relationships Among Heart Failure-Related Physical Symptoms, Social Support, Social Problem-Solving, Depressive Symptomatology, And Self-Care Behaviors In Individuals Living With Heart Failure, Lucinda Joy Graven
All ETDs from UAB
Introduction: Heart failure (HF) is a chronic condition that progressively worsens over time. The condition is more common in individuals over the age of 65 and commonly causes dyspnea, fatigue, orthopnea, nocturnal dyspnea, edema, and activity intolerance. Prior studies suggest a relationship between HF-related physical symptoms and depressive symptomatology in individuals living with HF. Depressive symptomatology in individuals with HF are linked with a higher mortality rate, decreased quality of life, decreased functional status, and disturbed sleep. Additionally, HF-related physical symptoms impact self-care in individuals living with HF. Previous studies have found that symptom severity and the associated decrease in …
The Impact Of Weight Status On The Adoption Of Self-Care Behaviors Among Heart Failure Patients, Bern'nadette Knight
The Impact Of Weight Status On The Adoption Of Self-Care Behaviors Among Heart Failure Patients, Bern'nadette Knight
All ETDs from UAB
Self-care is a major component of heart failure management. Excess weight is a disease that may negatively affect a patient's ability to effectively practice self-care. The project aimed to assess 1) the relationship between weight status and heart failure self-care behaviors and 2) the modification of the relationship between social support and heart failure self-care by weight status. This cross sectional study utilized baseline data from a cohort of African-American and Caucasian participants diagnosed with heart failure. The heart failure cohort was formed from three larger studies (n=690) designed to assess the relationships among social support, self-care behaviors and hospital …
